WILLIAM G. EHRHARDT, OF NEW YORK, N. Y.

SOUND=COLLECTOR FOR THE. EARS.

SPECIFICATION forming part of Letters Eatent No. 656,182, dated August21, 1900.

Application filed April 17, 1900. Serial No. 13,178. (No model.)

To all whom, it may concern:

Be it known that LWILLIAM G. EHRHARDT, a citizen of the United States,residing at New York, in the county of New York and State of New York,have invented certain new and useful Improvements in Sound-Collectorsfor the Ears, of which the following is a full and completespecification, such as will enable those skilled in the art to which itappertains to make and use the same.

This invention relates to sound-collectors for the ears; and the objectthereof is to provide an improved device or devices of this class whichare simple in construction and operation and which may be easily andcon- 7 veniently attached to the head, so as to avoid the necessity ofbeing held in the hand, as is the case with ordinary ear-trumpets.

The invention is fully disclosed in the following specification, ofwhich the accompanyin g drawings form a part, in which like referencecharacters designate the same parts in each of the views, and in which-Figure 1 is a side view of a head, showing the method of using myimproved sound collectors; and Fig. 2,a perspective view showing thesound-collectors removed from the head.

In the practice of my invention I provide two hollow devices A, whichare of the shape of the half of a truncated hollow cone, as clearlyshown in the drawings, and these devices may be made of metal, hardrubber, or any other suitable material, and each is provided, at oneedge or side thereof,with a longitudinallyarranged keeper B, throughwhich is passed a tape, cord, or similar device 0, on which thesound-collectors may be adjusted, as will be readily understood.

The tape 0 may be composed of elastic or any suitable material, and ifof elastic material it will be formed, as shown in the drawings, into acontinuous band, which is passed over or around the upper portion of thehead, as shown in Fig. 1, so as to hold the soundcollectors over theears, with the larger ends thereof directed forwardly, and if said tapeis not composed of elastic material it will preferably be divided, sothat the ends thereof may be tied to produce the proper adj ustment. 7

The smaller ends of the sound-collectors are closed, as shown at D, andthe larger ends open, and the edges or sides of the sound-oollectors areso formed as to lit the contour of the side of the head and the tape orband 0 will securely hold them in place, and by means of these devices Iprovide for the free use of the hands, as the sound-collectors when onceadjusted will remain in position as long as desired.

These devices are particularly adapted for use in theaters, at theopera, or at other public amusements by those Whose hearing isdefective; but it will be apparent that they may be used on any and alloccasions.

The said sound-collectors are also simple in construction and veryinexpensive, 'and it will be apparent that changes in and modificationsof the construction described may be made without departing from thespirit of my invention or sacrificing its advantages.

Having fully described my invention, I claim as new and desire to secureby Letters Patent 1. The herein-described sound-collectors for the ears,said collectors being shaped like the half of a truncated cone, andbeing hollow and open at one side and at the larger end and provided atone side or edge with a keeper or loop, and a tape or band which ispassed through said keeper or loop, substantially as shown anddescribed.

2. The herein-described sound-collectors for the ears, consisting ofdevices which approximately resemble the half of a hollow truncatedcone, which are open at one side, and at the larger end, and which areprovided with means for securing them to the head so as to inclose theears, substantially as shown and described.

3. The hereindescribed sound-collectors for the ears, consisting ofhollow devices which are shaped like the half of a truncated cone, andwhich are open at one side and at the larger end, the smaller end beingclosed, said devices being provided with means for securing them to thehead so as to inclose the ears, substantially as shown and described.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of the subscribing witnesses, this 16th day of April,1900.

WILLIAM G. EIIRHARDT.
